Black Point Volcano lies on the northern shore of Mono Lake. In the middle of the lake are the two islands: the dark Negit Island composed of a dark dacite, and the light Paoha Island composed of recently uplifted lake sediments and some volcanics. The Mono Domes, including Panum Crater, are on the far right. Ancient shore lines on the flanks fo Black Point Volcano are visible in the lower left. These shorelines formed during glacial highstands of the lake.
Black Point Volcano is noteworthy becuase it erupted underwater during a highstand of Mono Lake. Basaltic tephra was redistributed by water before being deposited.
Gigapans of these deposits include the following.
